connect(m_HelpAct, SIGNAL(triggered()), this, SLOT(OnHelp()));

实现槽函数：
void CXXX::OnHelp()｛
QString runPath = QCoreApplication::applicationDirPath(); //获取exe路劲。

QString helpName = "帮助文档.pdf";

QString helpPath = QString("%1/%2").arg(runPath).arg(helpName);

QFile bfilePath(helpPath);

if(!bfilePath.exists()){

return;

}

QString filePath = "file:///" + helpPath; //打开文件夹用filse:///,打开网页用http://

QDesktopServices::openUrl(QUrl::fromLocalFile(filePath));

｝
